Super simple, extra delicious, and perfectly sweet Chocolate Peanut Butter Millionaire Bars. Easy shortbread, made with nutty brown butter and flavorful brown sugar, baked and layered with sweetened peanut butter. Each sweet bar is covered in chocolate and finished with a sprinkle of flaky sea salt. Similar to a classic Millionaire Bar…but with a sweet, creamy peanut filling that makes them even more delectable. A fun addition to your Christmas table or Christmas Cookie Box

I shared a sneak preview of these over the weekend when I shared my Christmas Cookie Box. I can’t believe how many of you have messaged me since asking for the recipe! Of course, that got me very excited to share these simple but fun chocolate peanut butter bars. 

As crazy as it is, this is my first Christmas dessert using peanut butter. I thought about doing peanut cookies, but in end, I landed on these delicious bars that my family is excitedly waiting to try. 

It’s no secret that everyone in our family enjoys a chocolate peanut butter treat!

Which honestly is what inspired me to make these. Knowing how much everyone enjoys a peanut butter dessert, I figured these would be amazing handheld treats we could all enjoy and even have fun baking together. 

Actually back before we started the site, I used to take holiday cookie cutters, pour chocolate on the bottom, and then do a layer of peanut butter on top. The idea was to create holiday-shaped peanut butter cups, but they never quite worked out that well. 

These are similar, but with the addition of buttery brown sugar shortbread that creates an even yummier Christmas treat. Like a Millionaire bar but with sweetened peanut butter. 

And if you’re looking for a peanut-free Millionaire Bar, I already have a recipe for those. You can find them here! They’re yummy too, but we like this peanut butter adaption even more.

Here are the details

Start with the shortbread. I kept it simple, but I browned the butter, which is really key to adding delicious flavor to an otherwise flavorless base. Don’t skip! The nutty browned butter pairs so nicely with the flavors of the brown sugar and vanilla. 

While the shortbread bakes, make the peanut caramel layer, which really could not be simpler. I didn’t want to make it too sweet because I just didn’t feel it was necessary. So I opted out of using sweetened condensed milk and instead used maple syrup.

At this point, chill the bars to help the peanut butter set up. Then cut the bars into cute little rectangles or squares and cover them entirely in chocolate.

Yummy! Oslo is going to be obsessed with these.

And my mom is really looking forward to trying these as well. She tries to avoid sugar, so I know she will enjoy the fact that these are not too sweet! 

These would be a great addition to your holiday dessert tables or cookie boxes, something fun for people to snack on that isn’t a cookie! 

Plus, I just love that they look like mini presents!

Tip for Success

Make sure the bars are thoroughly chilled before dipping them into chocolate. This is probably my biggest tip. If the bars are frozen, the chocolate will quickly set up and be easier to work with. Trust me, freeze the bars, then dip them through the melted chocolate.

This tip works well for any chocolate covered dessert!

    Ok so I started looking through your Christmas cookie recipes so I could pick out 2 or 3 recipes to make for gifts but now I want to make ALL of them!! However, I think it’s fair to say millionaire bars are very near the top of my list. There’s just something so magical about the soft caramel, sweet chocolate and nutty bars that is hard to beat! So I’m definitely making these and I still have to narrow down my choices on the rest.

    Merry Christmas!


    1. Aw thank you Victoria! Hope you enjoy all the delicious Christmas treats this holiday season! Merry Christmas to you! 🙂 xT

    These are so delicious and always a huge hit, but i’m unable to get the beautiful clean edges that you have. Mine look like a mess! Any tips? Do you have a video for dipping into chocolate?

    These were so freaking good. My son and I made these for a super bowl party last night, and everyone could not stop raving about them.

    1. Hey Jessi,
      Happy Valentine’s Day! 💌 I appreciate you giving this recipe a try and sharing your feedback, so glad to hear it was tasty! xT

  6. Does the melted coconut oil go with the chocolate or the peanut butter????

    The instructions don’t specify if the chocolate gets the 1/4 cup or the 2T amount.

    1. Hi Molly,
      You are using 1/4 cup of coconut oil in step 4 and the 2 tablespoons of coconut oil in step 5. Please let me know if you have any other questions! xT

    1. Hi Kenzie,
